Required
The lower limit 94% confidence interval
First, calculate the mean




Next, calculate the standard deviation using:

So, we have:




For 94% interval, the z score is

So, the margin of error (E) is:




The confidence interval of the true mean is:

The lower limit (L) is:



and the upper limit (U) is



Answer:
Each point (or pair in a proportional relationship) must share the same difference
Step-by-step explanation:
The graph of a proportional relation is a straight line through the origin. Such a line has the same ratio of y/x everywhere.
A relation in which the difference is constant will be a straight line, but it won't be through the origin. Such a relation is not proportional.
